2 Technical Data TD E Important Notice: This booklet is designed to familiarize estimators and installers with proper sizing guidelines for residential and commercial generators. The information is not comprehensive, nor does it replace or supercede any material contained in any of the written documents shipped with the equipment. This booklet should only be used in conjunction with the Owner s Manual, Installation Manual and other technical documents shipped with each product. Always read all accompanying documentation carefully before attempting to install any generator, transfer switch or related equipment. How To Use This Booklet: Within this booklet, you will find electrical load information, plus an outline of generator surge capability, fuel pipe sizing, liquid propane tank sizing, and UPS / generator compatibility. The worksheet pages can be removed from the book and photocopied to create additional Onsite Estimating Sheets for use with individual jobs. Safety Information: Proper sizing of the generator is crucial to the success of any installation and requires a good working knowledge of electricity and its characteristics, as well as the varying requirements of the electrical equipment comprising the load. When analyzing the electrical load, consult the manufacturer s nameplate on each major appliance or piece of equipment to determine its starting and running requirements in terms of watts, amps and voltage. When choosing the generator output for commercial or industrial applications, select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 40 kilowatts, select a 50 kw genset). A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future. For safety reasons, Eaton recommends that the backup power system be installed, serviced and repaired by an Eaton Authorized Service Dealer or a competent, qualified electrician or installation technician who is familiar with applicable codes, standards and regulations. It is essential to comply with all regulations established by the Occupational Safety & Health Administration (OSHA) and strict adherence to all local, state and national codes is mandatory. Before selecting a generator, check for municipal ordinances that may dictate requirements regarding placement of the unit (setback from building and/or lot line), electrical wiring, gas piping, fuel storage (for liquid propane or diesel tanks), sound and exhaust emissions. If you have a technical question regarding sizing or installation, contact Eaton s Technical Service Center toll free at during normal business hours (8 a.m. to 4 p.m. CST). 2

8 Technical Data TD E UPS - GENERATOR COMPATIBILITY Passive (also referenced as standby or off-line) and Line- Interactive These technologies are most common for personal workstations and point of sale applications. They are typically single phase equipment with size ranges of 350 VA VA for passive and 500 VA to 5000 VA for line-interactive. Passive UPS s are the simplest type. Under normal conditions AC power passes straight through to the UPS load. When the input power supply goes outside of specifications, the UPS transfers the load from input power to the internal DC to AC power inverter. Passive UPS s do not correct for voltage or frequency deviations under normal operation. Line-interactive is similar to the passive technology except it has circuitry that attempts to correct for standard voltage deviations. Frequency deviations under normal power operation are not corrected. Equipment Notes: These devices tend to be electrically / harmonically very noisy. A single small UPS is not a significant concern, but applications with multiple UPS s can be problematic. Passive UPS technology typically has normal tolerances of 10-25% on voltage and 3 hertz on frequency. If the input source goes outside of these tolerances, the UPS will switch onto the UPS battery source. Some line-interactive units may have frequency tolerances factory set to 0.5 hertz. These units will need to have their frequency tolerance increased to a minimum of 2 hertz. Double-Conversion This technology is most common for critical load applications. Doubleconversion UPS s constantly rectify AC to DC and then invert the DC back into AC. This configuration results in an output that corrects for voltage and frequency deviations. There are single and three phase models covering small through large applications. Most UPS applications larger than 5000 VA use double conversion technology. This approach is also the preferred technology for generator applications. Equipment Notes: Double-conversion UPS s that are single phase or unfiltered three phase models tend to create a significant level of electrical/ harmonic noise. This is illustrated by harmonic current distortions that are greater than 35%. Minuteman UPS products could have current distortion of 8%. When three phase models are supplied with harmonic filters (current distortion less than 10%), this concern is no longer an issue. Generator Sizing Recommendation: Single phase models: Limit the total UPS loading to 25% of the generator capacity. Single phase Minuteman UPS models: Limit the total UPS loading to 50% of the generator capacity. Three phase models without filters (current distortion > 30%): Limit the UPS loading to 35% of the generator capacity. Three phase models with filters (current distortion < 10%): Limit the UPS loading to 80% of the generator capacity. Generator Sizing Recommendation: Limit the total UPS loading to 15% - 20% of the generator capacity.

10 Technical Data TD E Onsite Estimating Sheet Generator Sizing Instructions: There is not a single correct sizing solution. Following are several methods that, when mixed with good judgement, should result in an appropriately sized generator. Remember to consider load growth, seasonality, and effects of starting motors. As municipalities and states adopt the new 2008 NEC Electrical Code, there may be new sizing requirements, spelled out in the code book, which the installation technician must follow. Always check with the local inspection department to confirm which code cycle will affect your install. Never add Amps when sizing a generator. Convert Amps to kw and add kw to determine the required generator size. Power factors for various motor loads vary widely. Adding Amps without properly accounting for the power factor and/or mixing voltages will result in improperly sizing the generator. When motors start, they create a current surge that step loads the generator and creates a voltage dip. After selecting a generator, reference the generator s surge capability using table 3. Verify that voltage dip is adequate for the application. Most commercial applications should be limited to about 15% voltage dip and residential applications should be limited to a 30% voltage dip. Some applications utilize an uninterruptible power supply (UPS) to back up critical loads. Please read sizing guide for this load type. Measurement Method Use a clamp-on Amp meter or power analyzer to measure facility load levels. Clamp each leg separately and take the measurement during peak usage levels. 240V 1ø Applications: To determine peak usage in kw, add the highest Amp readings from the two legs, multiply by 120 and divide by 1,000. (L1 + L2)120 / 1000 Size the generator 10 to 20% larger than the peak measured load. 3ø Applications: Add the peak Amp readings from all three legs and divide by 3 to determine peak Amps. Multiply peak Amps by volts, multiply the result by (square root of 3), then divide by 1000 to convert Amps to kw. Peak Amps = (L1 + L2 + L3) / 3 kw = [(Peak Amps x Volts) x 1.732] / 1000* *Assumes power factor of 1.0 Size the generator 20 to 25% larger than the peak measured load. Peak Amps = Peak kw= Billing History Method Commercial Many commercial customers have a utility rate structure that has a peak demand charge. Using a year s worth of electric bills, size the generator 25% larger than the largest peak demand. Verify motor and UPS load compatibility: Peak Demand = Load Summation Method Enter running kw for all motor loads (except the largest) expected to run during peak load levels into table 6. Refer to table 1 for typical motor load sizes and electrical requirements. Enter kw for all non-motor loads expected to run during peak load levels into table 7. Refer to table 2 for typical residential loads and rules of thumb. Add the running motor load kw, non-motor load kw, and the starting kw of the largest motor load. Motor load running total (minus largest motor): (ref. table 6) Non-motor load total: (ref. table 7) Starting load from largest cycling motor: (ref. table 6) Total electrical loads: Select generator: Commercial (add 20 to 25% to total kw) Residential (add 10 to 20% to total kw) kw kw kw = kw Confirm that voltage dip is within acceptable limits by comparing motor LRA to generator surge capability (see table #3). Confirm UPS compatibility (see page 6). System Capacity Load Calculation If the local municipality or state you are in has adopted the 2008 NEC Code, you may be required to use this step. Article 702 of the 2008 NEC includes a new requirement for sizing (702.5B). If no other method for sizing is acceptable, sizing of the generator shall be made in accordance with Article 220 of the NEC. The system capacity estimating sheet will guide you through this process.
